Question

trangle PQR and trangle SQR are Isoseles find angle PQR and angle PRQ​

Answer 1

Answer:

Step-by-step explanation:

in the figure

angleQ =angle R....(since , sidePQ is equal to sidePR)

let angleQ =angleR =a°

therefore,angleP +angleQ + angle R = 180°......(sum of all angle of triangle os 180°)

30°+a+a=180°

30°+2a=180°

2a=180-30

2a=150°

a=75°

angleQ=angleR=75°

similarly in ∆SQR,

angleSQR=angleSRQ=55°

Now, AngleQ =anglePQS+angleSQR

Therefore , 75°=x°+55°

x=75°-55°=20°

x=20°
